MIXING-AND VAPORIZING DEVICE FOR MOTORS- A SPECIFICATION forming part ofLetters Patent No. 761,192, dated May 31, 1904.

Application filed October 16, 1901. $erial No. 78,783. (No model.)

To all whom it may concern.-

Beit known that 1, JAMES E. BEAN, residing .at Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented a new and usefulImprovement in Mixing and Vaporizing Devices for Motors, of which thefollow1ng 1s a description, reference being had to the accompanyingdrawings, which are a a part of this specification.

My invention has relation to improvements in mixing and vaporizingdevices for motors, more especially, although not necessarily, for

, gasolene-motors.

The primary object had in view is to provide a simple constructionwherein the pump ordinarily used for sucking the gasolene or othervapor-gas liquid from a tank is entirely dispensed with'and a simplemechanism employed in lieu thereof, which shall'be capable of drawingthe liquid from the tank and conducting said liquid to the mixingportion of the device, there to be mixed with and atomized by theinflowing air.

A further object resides in providing a simple construction wherein thesupply of gasolene may be readily controlled and set to .feed a desiredquantity of liquid into the mixinafter more fully set forth;

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof my improvements. Fig. 2 is a plan view of the parts above the tank.Fig. 3 is an end View of Fig.

2, andFig. 4 is an enlarged sectional view of the oil-feeding device.

Referring to the drawings, the numeral 4 indicates a tank for containingthe gasolene or other vapor-gas-producing liquid. In the scale, asclearly shown in the drawings.

side of said plate.

extends for a desired distance downwardly in the tank, preferably tonear the bottom of said tank. Within the coupling 9 is formed avalve-seat 11, against whiehan upwardlyopening valve 12 is seated, saidValve provided with a depending guide-stem 13.

Extending across the interior of pipe 7 and communicating with thenipple 8 is a tube 14. This tube is provided at diametrically oppositepoints with openings 15 15. If desired,

only one opening 50 may be provided and successful results obtained.Rotatably fitting in the tube 14 is a plug 16, said plug being tubularfrom its lower end upwardly for a desired distance to form a channel 17The upper end of this channel is intersected by a transverse opening 18.The plug extends outwardly from the upper surface of the pipe and hassecured to its upper end an index arm 19, which is adapted to work overthe face of a segmental plate 20, said plate provided upon its upperface with a' graduated The end of the arm 19 is extended beyond theouter edge of the segmental plate and is bent around said outer edge andthen upwardly, so that its extremity will contact with the under Thiscontacting extremity of the arm on the under side of the plate worksover a series of indented marks 21, as shown by dotted lines in Fig. 2,said marks being graduated to conform to the scale-marks on the upperside of the plate and serve as a rack to hold the arm at adjustedposition.- Secured to the end of the pipe 7 is a coupling 22. Thiscoupling may be secured in any desirable manner; but I prefer to connectit in the manner shown in the drawings, wherein the end of the pipe 7 isshown as having exteriorly threaded thereon a collar 23, said collarprovided at its outer end with a shoulder 24. A connecting band or ring25 surrounds the joint between the pipe and coupling, and one end ofthis band or ring is provided with a shoulder 26, which engages theshoulder 24E of the collar. The opposite end of said ring or band isprovided with female threads which engage male threads on the end of thecoupling. This particular form of connection provides a means for readyadjustment in case the fittings are not perfect.

Within the coupling 22 is a partition 27, the horizontal portion of saidpartition provided with an opening forming a valve-seat 28. Normallyclosing this opening is a valve 29,

which is provided with an upwardly-extending guide-stem 30, said stemfitted and guided in a tubular extension 31. The guide-stem issurrounded by a' coiled spring 82, which is confined between the upperside of the valve and the under side of the tubular extension. Connectedto the outer end of the coupling 22 is a pipe '33, which connects withand conducts the mixture to the cylinder (not shown) of the engine andwhich cylinder may be of any of the usual and well-known forms ofconstr'ucti'on. I

In the operation of the invention the plug 16 is turned so that itsopening 18 is brought intoregistration with the openings 15 15 ofthetube 1 1. If the maximum amount of gasolene to which the device iscapable of feeding is desired, theplug is turned so that the opening 18is in full'registratio'n with the openings 15, or if it, is desired tofeed a less quantityof gasolene the plug is turned so that there will beonly a partial registration of said openings.

The graduated scale on the segmental plate determines the extent thehandle 19 is required to be turned in order'to provide for the feed of agiven amount of gasolene, and

when the handle is turned to the proper position it is held stationaryin that position until it desired to change the feed. It is obvious thatinstead of the openings 18 and 15 extending through both sides of theplug 16 and tube 14c, respectively, they may extend through 'one sidethereof only and such openings arranged to register at "any point wherea suction would be produced therethrough.

When the engine mechanism is started, the

suction created by the piston on its reciprocation in one direction willovercome the tension' of the spring 32 and raise the valve 29. Thissuction will also draw in air through the open end 'of the pipe 7, andthe air so drawn in andi-ushing past the tube l4will cause the gasoleneto be drawn up in the'tube 10, the ascending gasolene raising thecheck-valve 12,

and flowing above said valve into the passage 17 of the plug 16, thencethrough the opening 18 of said plug, and'out of the openings 15 of thetube 14 and into the pipe 7. The checkvalve 12 of course serves toprevent the backflow of the gasolene. The air and gasolene now comminglein'the pipe 7, the air having the effect of atomizing and vaporizing thegasolene. The mixture now flows into the coupling 22, thence through thevalve-opening 28 into pipe 83, and finally through said pipe to thecylinder of the engine.

From the construction above described it will be seen that I provide asimple means for drawing the gasolene from the tank without thenecessity of employing a suction-pump,

. as ordinarily used, and I also provide a most 'efficient means formixing gasolene and air and atomizing and vaporizing the gasolene,together with provision 'for accurately regulating the amount ofgasolene drawn from the tank.

The small holes 15 15 and 18 are quite liable to become clogged up withdirt, and there by impair the working of the device. It is to guardagainst this that I provide for the removability of the plug 16. Inorder to remove said plug, all that is necessary to be done is to turnthe handle 19 until the extremity thereof which is beneath the plate 20has passed either end of said plate. The plug can then be readilyremoved and the passage 17 and the opening 18 thereofcleaned withoutdifficulty, When this plug is thus removed, it is also evident thataccess may be readily obtained to the holes 15 by means of a wire orother device inserted through the end of the pipe 7 andthrough saidholes 15.

The extremity of the handle 19,which bears against the under side of theplate 20,.not only forms a means icy-engagement with the indentations 21for holding the handle in adjusted position, but said end of .the handlealso prevents the plug frombeing removed until the handle is turnedsufliciently far in either direction for the extremity thereof to cleareither end of the plate 20. I would also call attention to the fact thatby providing the coupling 9 at the upper end of the tube 10, saidcoupling having a threaded connection with the nipple 8, the distancethe tube .10 extendsinto the tank 1 may be readily regulated. I wouldfurthermore call attention to the fact that I- prefer to provide in theouter end of the pipe 7 a thin partition 34, the rear edge of saidpartition almost touching the tube .14; and being in line withthe outeropening 15 of said tube. Experience has demonstrated that by theemployment of this partition the capacity of the device for drawing thegasolene upwardly into the pipe? is greatly augmented.
